Normal

Normal Adult EEG

The first step in learning how to interprete the adult EEG is to learn how to recognize and describe what normal looks like. If you are a novice and have only a few minutes before one of your teachers plans to pull up an EEG and grill you about what you see, then take a look at the following, and in this order:

awake (double banana montage)

blinking

posterior dominant rhythm

muscle artifact

stage 2 sleep (transverse montage)

vertex waves

sleep spindles

K complex

You will also want to learn what someone means when they ask: "what is the background rhythm?"
